Abstract: PURPOSE:To form a heavy metal domain in a prescribed domain with a high accuracy by a method wherein an N type domain is formed in a peripheral part of a P type domain in which a heavy metal domain is to be formed and a heavy metal is introduced to form the heavy metal domain in the P type domain. CONSTITUTION:A P type domain 12 is formed in an N type semiconductor substrate 11. A ring shape N type domain 15, into which phosphorous is introduced as an impurity, is formed in a periphery part of the domain 12. After an oxide film 13 is formed on the surface of the substrate 11, a prescribed part of the film 13, inside the domain 15, is removed and a gold film 14 is formed by deposition. A gold diffusion domain is formed by diffusing gold from the film 14 into the domain 12 in a high temperature atmosphere. A solid solubility of gold in the domain into which phosphorous is introduced is very large. Therefore, gold is not diffused to the horizontal direction so that it is diffused into the required domain only. Partial precipitation of gold near the edge of the domain 12 is reduced and a leakage current when a reverse bias is applied to a diode is significantly reduced.
